On Wednesday, a few hours after the horrific knife attack on two British Jewish men in Golders Green, north London, a video appeared on Telegram, apparently from the group called Harakat Ashab al-Yamin al-Islamiya, making an unsubstantiated claim of responsibility.
It follows a string of arson attacks around Europe that have been claimed by the group, whose name translates as the Islamic Movement of the Companions of the Right. But unlike some of the previous claims that appeared to show footage taken by the perpetrators, Wednesday’s video used footage that was already in the public domain.
